"An improved fly wheel"
APPLICANT
VEKARIA JAYANTIBHAI of Khad Vanthali, Gondal, Dist. Rajkot, Gujarat, INDIA.
The following specification particularly describes the invention and the manner in which it is to be performed.



A flywheel absorbs energy released during the power stroke and releases it during remaining three strokes so as to keep the engine running,, Flywheel also helps the machine to avoid any j e r k s a t t h e b e g i n n i n g a n d e n d o f t h e s t r o k e » 11 a 1 s o h e 1 p s transmission mechanism to absorb sudden changes in load.
The existing flywheels, being used in diesel engines are circular solid round blocks made of iron without any passage for air,. Solid surface of the wheel doesn't allow efficient air-cooling as-only mode of cooling is fins for the flywheel. Also, air cannot reach to the cylinder, which can provide cooling to the cylinder„
Solid block of the flywheel results in the weight concentration near the center of the flywheel. This reduces energy storage capacity of the flywheel.
Yet another disadvantage is that ineffective and insufficient cooling results in early wear and tear of the engine parts and reduces life of the engine.
(OBJECTS (OF TOE INVENTION
An object of this invention is to prepare a novel construction of a flywheel for use with a diesel engine.
Another object of this invention is to propose a flywheel for use with a diesel engine which cools itself better compared to con v en t i on a 1 f1ywh e e 1 s.

Still another object of this invention is to propose a flywheel for use with a diesel engine which provides better cooling to the cylinder of the engine.
Yet another object of this invention is to propose a flywheel for use with a diesel engine which has an effective weight distribution at the circumference of the flywheel increases energy storage capacity of the flywheel.
A further object of this invention is to propose a flywheel for use with a diesel engine which has a higher weight concentration at the circumference of the flywheel reduces vibration in the engine, which again reduces wear and tear of the engine parts and results in longer life for the engine and its parts.
DESCRIPTION OF INVENTION
According to this invention there is provided an improved fly wheel which can be employed with a diesel engine comprising of a centre section adapted to be held to a shaft, periphery section having plurality of fins mounted in a spaced relationship thereon characterized by plurality of ribs equally spaced from each other extending between said centre and periphery section, spaced disposed between adjacent ribs.

DESCRIPTION OF INVENTION WITH REFERENCE TO ACCOMPANYING DRAWINGS
Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawing and wherein.
Figure 1 shows the flywheel of the present invention.
Referring to Figure 1, flywheel 1 of the present invention may be made of any suitable metal, such as mild steel, and comprises a centre section 2 adapted to be held to a shaft (not shown) and a peripheral section 3. A plurality of fins 8 disposed in a spaced relationship to each other are provided in peripheral section 3.
Specifically, according to the present invention, a plurality of ribs 4 disposed in a spaced relationship are provided between centre section 1 and peripheral section 3. Ribs 4 are disposed in a spaced relationship to each other and preferably equidistant from each other. Further, ribs 4 itself comprises a proximal section 5 and a distal section 6, the proximal section 5 being of a greater height in comparison to that of distal section 6.
Further, in accordance with this invention, slots 7 are provided between adjacent ribs 4. Slots 7 are also provided in a spaced relationship to each other.
Several advantages ensue by the flywheel of the present invention.
-4-

The slots 1 provided in the wheel 1 provide better cooling to the flywheel i„ Also, it allows atmospheric air to reach to the cylinder and results in better cooling of the engine as well,, Better cooling of flywheel 1 and cylinder results in better ef f i c iency of th e eng ine «
Ribs 4 and slots 7 in flywheel 1 push weight concentration towards circumference of the flywheel, away from the center of the flywheel. Weight concentration at the circumference improves energy storage capacity of flywheel i.
Effective cooling through flywheel 1 results in longer life of the engine dt\e to reduced wear and tear in the engine.

ICLAIM


1. An improved fly wheel which can be employed with a diesel engine
comprising of a centre section adapted to be held to a shaft,
periphery section having plurality of fins mounted in a spaced
relationship thereon characterized by plurality of ribs equally
spaced from each other extending between said centre and
periphery section, spaced disposed between adjacent ribs.
2. A flywheel as claimed in claim 1 comprising 6 said ribs.
3. A flywheel as claimed in claim 1 wherein each rib comprises a proximal and distal section, said proximal section having a height greater than the distal section.
4. A flywheel for use for example with a distal engine substantially as herein described and illustrated.
